System and methods for adjusting variable geometry, height, weight distribution dynamics in orthotic devices and equipment

ABSTRACT

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

No. 14/543,883-, the contents of which are incorporated byreference herein.

FIELD OF THE INVENTION

The invention relates the field of equipment and more particularly todevices, apparatus and equipment whose degree of stiffness andflexibility may be varied or dynamically controlled.

BACKGROUND

There is a need for varying and adjusting the flexibility and stiffnessof associated devices, apparatus and equipment to customize to a user'sunique needs, and to the requirements of a particular task or desiredoutcome.

For example, in recent years, as it relates to the category of sportsand fitness equipment, manufacturers and marketers have increasinglyturned to different kinds of methods to enhance the customization andperformance of sporting and fitness equipment. In some cases, entirelines of sporting equipment have been developed whose stiffness orflexibility characteristics are different from each other and aredesigned to be matched to the user's unique needs. Such differences,however, may be enough to give the individual equipment user an edgeover the competition in that the equipment can be more personallycustomized, matched to a desired goal, and, therefore, enhanceperformance.

Until now, the user may choose a particular piece of sporting or fitnessequipment having a desired stiffness or flexibility characteristic and,during play, switch to a different piece of sporting equipment that isslightly more flexible or stiffer to suit changing playing conditions orto help compensate for weariness or fatigue or some other anomaly thatprevents optimum performance. Such switching, of course, is subject tothe availability of different pieces of sporting or fitness equipmentfrom which to choose, at the precise moment the change or adjustment isneeded. In many cases, the availability is limited due to cost and overall impracticability.

Additionally, subtle but important changes in the stiffness orflexibility characteristics of sporting or fitness equipment may not beavailable between different pieces of sporting equipment, because thecharacteristics may be set by the manufacturer from the choice ofmaterials, design, etc., and to change the characteristics would beimpossible, as such customization isn't offered to the user. Further,the user must have the different pieces of sporting equipment nearbyduring play or they are essentially in practice unavailable to the user.

Thus, it can be seen how the lack of adjustability in stiffness andflexibility may adversely affect optimum performance of a device,apparatus, and equipment.

Turning to additional types of devices, apparatus and equipment, it canbe seen how the lack of a practical means of adjustability in stiffnessand flexibility may adversely affect performance.

Medical Devices, Apparatus, and Equipment

Medical devices, apparatus and equipment, such as braces that are usedfor supporting injured limbs, require the flexibility of the device tobe adjusted based on the degree of the injury, type of surgery, and theprogress of the healing of the injured party. Further, there is a needfor on-going protection even after recovery. Yet the degree ofadjustability of braces is limited, and, in most cases, fixed.Adjustability of the flexibility of the brace the brace to the specificneeds and requirements of the user, may enhance recovery and protectionfrom further injury.

Fitness Devices, Apparatus, and Equipment

Fitness equipment, apparatus and devices require the creation ofdifferent amounts of resistance to perform the exercise. For example,with free-weight training the user must change the weight levels toprogressively increase the resistance that the user experiences. Thisoften involves the continued and time consuming adjustment of equipmentthrough an exercise cycle and makes changes impractical at best, and atthe least a hassle.

Numerous heavy metal plates, large oily machines, weights, rubber bands,and singular resistance rods are the many known forms of fitnesstraining. When the user changes resistance/weight or machine during anexercise set, it is time consuming and interrupts the user'sconditioning.

Running Shoes, Training Shoes, Basketball Shoes

The transmission of the shoe wearer's strength (power) from their legsinto the ground is directly affected by the sole stiffness of the shoe.Runners may gain more leverage and, thus, more speed by using a stiffersole. Basketball players may also affect the height of their jumpsthrough the leverage transmitted by the sole of their shoes. If the soleis too stiff, however, the toe-heel flex of the foot is hindered. Thus,athletic shoes are tailored, by the manufacturer, to the particularsport to which the shoe is to be used. In some case, it may be possiblefor the user have the ability to tailor the sole stiffness to his/herindividual weight, strength, height, running style, and groundconditions. However, this process is performed by the manufacturer andis beyond the ability of the average user. Golf

Golf clubs may be formed of graphite, wood, titanium, glass fiber orvarious types of composites or metal alloys. Each material varies tosome degree with respect to stiffness and flexibility. However, golfersgenerally carry onto the golf course only a predetermined number of golfclubs. Varying the stiffness or flexibility of the golf club is notpossible, unless the golfer brings another set of clubs. Nevertheless,it is impractical to carry a large number of golf clubs onto the course,wherein each club having a slight nuance of difference in flexibilityand stiffness than another. Golf players prefer taking onto the course aset of clubs that are suited to the player's specific swing type,strength and ability.

Hockey

Hockey (hockey includes, but is not limited to, ice hockey, streethockey, roller hockey, held hockey and floor hockey) players may requirethat the flexure of the hockey stick be changed to better assist in thewrist shot or slap shot needed at that particular junction of a game orwhich the player was better at making.

Younger players may require more flex in the hockey stick due to lack ofstrength; such flex may mean the difference between the younger playerbeing able to lift the puck or not when making a shot since a stifferflex in the stick may not allow the player to achieve such lift. Inaddition, as the younger players ages and increases in strength, theplayer may desire a stiffer hockey stick, which in accordance withconventional means the hockey player would need to purchase additionalhockey stick shafts with the desired stiffness and flexibilitycharacteristics. Indeed, to cover a full range of nuances of differingstiffness and flexibility characteristics, hockey players would haveavailable many different types of hockey sticks. Even so, the hockeyplayer may merely want to make a slight adjustment to the stiffness orflexibility of a hockey stick to improve the nuances of the play; whichis not possible with conventional technology

Tennis

Tennis players also may want some stiffness and/or adjustability intheir tennis rackets and to resist unwanted torsional effects caused bythe ball striking the strings during play. The torsional effects may bemore pronounced in the case where the ball strikes near the rim of theracket rather than the center of the strings.

Lacrosse

Lacrosse players use their lacrosse sticks to scoop up a lacrosse balland pass the ball to other players or toward the goal. The stiffness orflexibility of the lacrosse stick may affect performance during thegame.

Other Racket Sports

Other types of racket sports also suffer from the drawback of beingunable to vary the stiffness and/or flexibility of the racket during thecourse of play to suit the needs of the player at that time, whetherthose needs arise from weariness, desired held positions, or trainingfor improvement. Such racket sports include racquetball, paddleball,squash, badminton, and court tennis.

For conventional rackets, the stiffness and flexibility is set by themanufacturer and invariable. If the player tires of such characteristicsbeing fixed or otherwise wants to vary the stiffness and flexibility,the only practical recourse is to switch to a different racket whosestiffness and flexibility characteristics better suit the needs of theplayer at that time.

Skiing, Snowboarding, Snow Skating, Ski-boarding

Skis are made from a multitude of different types of materials anddimensions, the strength and flexibility of each type differing to acertain extent. Skis include those for downhill, ice skiing,cross-country skiing and water-skiing. For soft snow conditions, therider may want to have more flexibility so as to allow the board tofloat. For icier conditions, the rider may want to stiffen the highbackto provide greater leverage and power, which results in greater edgecontrol.

Bicycle Shoes

Bicycle specific shoes are rigid and may or may not be attached tobicycle pedals usually through a binding or clip mechanism thatprohibits the shoe from slipping of the pedal. The shoe is positioned onthe pedal so the ball of the foot is directly over the pedal. Therider's foot flexes as the pedal moves. However, the bicycle shoe isdesigned for pedaling and walking in these shoes is uncomfortable.

Fishing Rods

Fishing rods are flexed for casting out a line. The whip effect from thecasting is affected by the stiffness or flexibility of the rod.Depending upon the fishing conditions and the individual tastes of theuser, the user may prefer the rod to be either more flexible or stifferto optimize the whip effect of the cast and to deal with wind, current,types of fish, and the like. Thus, the user must select the type offlexibility or stiffness when purchasing the fishing rod.

Fins

Diving and swimming fins provide different degrees of stiffness that arefixed, and unchangeable. However, the need to have more flex or lessflex and, thus, control fin bend is dependent on the changingconditions. Optimum performance that matches the conditions may bepossible with dynamically adjustable fin spine(s). It would also beadvantages in that the swimmer/diver would not be unnecessarily fatiguedif they had proper matching flex to the conditions.

Sailboating and Sailboarding

Masts of sailboats and sailboards support sails. In many cases the usersmust adjust the amount of sail that is hanging from the mast accordingto the weather conditions to prevent damaging the mast caused by stresson the mast.

Canoeing, Rowboating and Kayaking

Paddles for canoes, row boats, and kayaks are subjected to forces asthey are stroked through water. The flexibility or stiffness of thepaddles, while different depending upon its design and materials, isfixed by the manufacturer. Thus, a rower who desired to change suchcharacteristics would need to switch to a different type of paddle.Carrying a multitude of different types of paddles for use with a canoe,row boat or kayak, however, is generally impractical for the typicalrower from the standpoint of cost, bulk and storage.

Lawn Rake

There are times when the flex of a rake's tines are either too flexibleor too stiff for the task at hand, be it for raking gardens, light leaf,matted thatch, wet grass, debris. Often the user has to purchase asecond rake to accommodate these additional needs.

Orthotics for providing corrective positioning of the foot whilewalking, running or participating in sports is generally custom fittedfor the user. This typically involves the characteristics of the userbeing measured by a doctor to determine the needed correctiveconfiguration. These custom fits are typically a static solution.Orthotics may then be fabricated based on the determined correctiveconfiguration.

Corrective orthotics are relatively expensive to purchase, are often notincluded for health insurance reimbursement and are time consuming inpreparing. Most important, the final product is always static andnon-dynamic. There also remains the issue of patient break-in, which canbe uncomfortable and even painful as the foot is manipulated to thedemands of the orthotic because of the customized orthotics arenon-dynamic and static in shape.

Conventional non-prescriptive orthotic offerings consist mainly ofcushioned insoles, which have limited palliative benefits that areshort-lived but are not biomechanically corrective. There are fewerproducts that attempt to provide the wearer non-dynamic correction tobiomechanical anomalies without going to see a doctor.

Thus, with corrective orthotics, a user may, in time, experience lesspain from bio-mechanical issues when walking, running or participatingin sports. They also attempt to limit the potential for long term,chronic maladies of the feet, ankles, knees, hips, and back.

In addition, users that do not require corrective orthotics may use acushioning insole in order to provide relief or prevent pain whenparticipating in exercises that apply significant pressure on the foot.

Cushioning insoles are generally composed of a gel-type material thatdistributes the user's weight over the surface of the foot. However, thecushioning insole is general in size according to the user's shoe size,and is not bio-mechanically corrective.

However, the current state of customized orthotics is one that isexpensive and/or not dynamically adapted to changing conditions that theuser may experience while walking or running.

Hence, there is a need in the industry of an orthotic system thatprovides the user with the ability to customize or adapt their orthoticsin order to provide not only a comfortable fit during differentactivities but one that is bio-mechanically dynamic and adjustable bythe user's unique structural demands.

SUMMARY OF THE INVENTION

The invention relates to a variable resistance beam or rod that maydynamically control the stiffness and flexibility of devices, apparatus,and equipment. The resilient rods, beams or shafts of solid, semi-solidor hollow construction produce resistance and variable resistances whenorientated in a direction of x, y, z plane or combination of planes in360 degrees of rotation or bending movement.

The variable resistance rod (VRB) technology may be incorporated intodifferent equipment (sports & fitness, lawn, medical, etc.) that requiredifferent degrees and direction of stiffness and flexibility, whereinthe different degrees of stiffness and flexibility may be controlled inthe field in real time by means of a selector, a worm gear, or othermechanical methods to affect a rotated orientation of the variableresistance rods, or by simple hand placement in relation to the fulcrumindicated by an indicia of color, number, symbol or other means.

One aspect of the invention resides in a resilient or resistance rodacting to create variable resistance that incorporates a selectable oradjustable flex resistance by means of hand position and placement.

One aspect of the invention resides in a resilient rod, beam or shaft,including at least one spine, extending substantially the length of therod, beam or shaft, that provides for variable degrees of flexibility ofthe rod, shaft or beam depending upon the orientation of the spine withregard to a direction of flex

One aspect of the invention resides in equipment that adjusts to providevariations in stiffness and flexibility. The equipment may have a rod,beam or shaft with an elongated cavity or rod, an elongated flexureresistance spine, one, two or more locking elements that secure the rod,shaft or beam against rotation at spaced apart locations within thecavity. The rod, shaft or beam is stiffer and less flexible in onedirection than in another.

Another aspect of the invention resides in sports equipment thatprovides variations in stiffness and flexibility. The sports equipmentmay have an elongated cavity, and a means imparting stiffness andflexibility variations within the cavity so the sports equipment becomesstiffer, and less flexible, in one direction than in another, and one ormore locking elements that secure the means against rotation in spacedapart locations within the cavity.

A further aspect of the invention resides in a method of varyingstiffness and flexibility, comprising providing equipment (e.g., sports& fitness, medical, footwear & sneakers) having an elongated cavity;imparting stiffness and flexibility variations within the cavity so thatthe equipment becomes stiffer and less flexible, in one direction thanin a different direction, and securing against rotation at least onelocation within the cavity while imparting stiffness and flexibilityvariations.

An additional aspect of the invention resides in a resilient shaft orbeam acting alone to create variable resistance that incorporates aselectable or adjustable flex resistance by means of varying handposition and placement on the resilient rod in relationship to thefulcrum of the bended rod.

An advantage of the present invention is the ability to provide constantand consistent flex adjustment. This advantage arises from theadjustment being locked in at the ends of the shaft and, depending uponthe application, at one or more additional locations through the lengthof the shaft.

A resilient rod acting alone is also embodied to create resistance thatincorporates adjustable flex or resistance by means of hand positionand/or specific rotation for means of exercise employing progressivedynamic resistance, which relates to the advantages in exercise ofvarying degree weight and resistance through a particular cycle.

The present invention embodies flexible materials and devices that formgeometries that conformally map or dynamically contour to footstructures in proportion (i.e., ergonomically conform, deform, and/orchange shape) to a mechanical setting of a Variable Resistance Beam(VRB) resistance or suspension range settings in balanced proportion todownward foot loading.

In accordance with the principles of the invention, VRBs act asadjustable resistance cantilevers to provide a selectable range ofdynamic and reactive suspension to the foot, ankle and lower extremityto bio-mechanically support bone, connective and musculature structuresof the foot.

In accordance with the principles of the invention one or more VRBs areapplied to orthotic structures to support the foot, for example in thearch. The invention generally delineates one or more VRBs per zone tobio-mechanically affect, support, correct and/or enhance any imbalanceof the lower extremity or foot.

In accordance with the principles of the invention, one or more VRBs orzones can be employed to correct and support the bio-mechanical needs ofa wearer, a patient, an athlete and/or soldier. Typically one or moreVRBs are used to dynamically support the mid arch of the foot and/or inconjunction with up to 4 or more VRBs or zones are employed topositively bio-mechanically correct imbalances or enhance athleticperformance of the front right/left and rear right/left sections of thefoot.

In accordance with the principles of the invention, a flexible orthoticshell and/or mid arch material (e.g., polymers, copolymer blends,polypropylene, polyethylene, toprelle molded EVA, durometer rangedfoams, et al.) with adaptable geometry may be connected to acorresponding VRB to impart selective, reactive and correctivereal-time, vertical bio-mechanical support, wherein the VRB may impartincreasing or decreasing vertical height to meet the individual'sergonomic arch shape and bio-mechanical arch support requirements.

In accordance with the principles of the invention, the uniquebiomechanics feature of selectable dynamic suspension coupled to producea conformal adapting orthotic shell geometry to support the foot indirect proportion to foot loading is called self or auto leveling.

DETAILED DESCRIPTION OF THE INVENTION

The object of the present invention is to adjust the flexibility andthereby the resistance of a rod by hand positioning in relationship tothe fulcrum of rod; or by bending a rod and spine within the shaft; orby bending a single solid rod; or both the bending of an outer beam andan inner beam in another example. This affects the longitudinal flex andthe kick or hinge point of flexure where maximum flexure bending forcesarise, depending on the hand position or anchor point in relationship tothe fulcrum.

A shaft includes any tube-like structure by itself, attached to theoutside of another surface or incorporated within a structure. Examplesof a tube-like shaft by itself include hockey sticks, golf clubs,lacrosse sticks, pole vaulting poles, fishing rods, sailboard/sailboardmasts, canoe/kayak paddles or oars, baseball bats, archery bows, tennisracquets and exercise machine tensioning rods. Examples of products towhich a tube-like shaft might be attached externally include skis,snowboard bindings and bicycle frames.

A beam or rod includes any solid, semi-solid or hollow elongatedstructure or rod, wherein the rigidity of the beam or rod is dependentat least upon the thickness of the material constructing the beam andthe type of material. In the case of hollow beams or rods, the rigidityof the beam is also dependent upon the thickness of the wall forming thebeam or rods and the material constructing the wall.

A spine includes any longitudinal structure whose flexure is differentin one plane than another, in any increment of 0 to 90 degrees. This canbe achieved using many materials. Examples of design shapes that havethis property include, but are not limited to, I-beams, ovals, stars,triangles, rectangles, stacked circles, ellipses, etc. The spine may besolid or hollow in construction and utilize combinations of differentmaterials and material thicknesses to achieve the preferred flexibilityprofile and characteristics.

In this illustrated example, the resistance to thebending force is maximum when the orientation of the inner splines isparallel to the bending force and minimum when the orientation of theinner splines is perpendicular to the bending force.

FIGS. 1F(a)-(c) further illustrate that the type VI VRBs 100 may also beof a cylindrical or a conical shape.

FIG. 1G(a)-Fig. (d) illustrate an exemplary embodiment of a type VII VRB100 beams having a rectangular cross-section 135. As shown therectangular cross-section may be sized in different ratios (e.g., 4:3,2:1) to provide different resistance to bending force. For example, in acase of a 2:1 ratio cross sectional area, the resistance to a bendingforce applied to the greater side is twice as great at that of thelesser side. The rectangular type VII VRB 100 may be solid or hollow asdesired.

Additionally, the resistance rods (VRBs) may include a plurality ofgraduated indicia that indicate bending resistance by measurement of afulcrum distance from an anchored position to a hand position[s], asshown.

Thus, in one aspect of the invention, rods with symmetrical crosssections vary their bending resistance by shortening and lengthening thearc length, from fulcrum to anchor point by hand position per indicia.

In another aspect of the invention, rods with asymmetrical crosssections may increase or decrease their bending resistance by rotationof the elongated orientation with respect to a bending force, whilemaintaining the same hand position or fulcrum length.

FIG. 2(a) and FIG. 2(b) illustrate the various fulcrum changes throughhand placement. Each new hand position provides different resistances.VRB 205 illustrates the variables resistances from a cylindrical beam,rod or bar. VRB 210 illustrates the variable resistances from a type IIVRB 100 beam, with added geometric spines, indicating, in this instance,the two-three times increase in pull resistance per identical handpositions along X/Y planes.

Table 1 illustrates exemplary resistance levels for differentconfigurations of the VRBs shown in FIG. 1(a) and FIG. 4 for a knownmaterial. In this case, resistance levels of VRB of 54 inch length,including 6 grip sections, each grip section being 3 inches for 9/16, ⅝and ¾ inch nominal VRBs are determined.

As shown in Table 1, the resistance level increases with the addition ofa geometric spine in this example. In addition, by shortening orlengthening the arc length/fulcrum during bending of the beam theresistance may be decreased or increased.

TABLE 1 Distance 9/16 inch thick bar ⅝ inch thick bar ¾ inch from NoWith Spine No With Spine thick bar fulcrum Spine Min/Max Res SpineMin/Max Res No Spine 51 7  8/15 10 11/21 22 48 8  8/16 11 12/23 24 45 9 9/18 13 14/25 26 42 10 10/20 14 15/28 29 30 11 11/22 16 17/32 33 36 1213/26 18 20/37 38

Also shown, the resistance level increases as the material thicknessincreases. In addition, the resistance level increases from a minimum toa maximum value as the orientation of the spine with respect to thedirection of the flex increases.

Hence, the resistance level that may be achieved at each hand leveldepends on the thickness of the VRB and the material composing the VRB.Although not shown it would be recognized that the resistance level mayfurther be based on whether the VRB is hollow. With a hollow VRB, theresistance of the VRB depends on a thickness

FIG. 2A(a)-FIG. 2A(f) Illustrates a comparison of a symmetric orbasically round and an asymmetric or elongated cross sectional VRB 100rod held at two positions.

As the fulcrum length or distance between the fixed hand position 215and the moving hand position 220 increases, the resistance decreases. Asthe distance between the anchored hand position and the moving handposition decreases, resistance increases.

FIG. 3(a)-FIG. 3(c) illustrate a VRB 100 with an outside diameter withmarked sets of indicia that specify the range of flexural resistancesproportionate to the tensile strength of the beam material and fulcrumlength per hand position[s] for symmetric or basically round (1 set) and(2 set) asymmetric or elongated cross sections.

FIG. 3(a)-FIG. 3(c) illustrate a side view 300 of an exemplaryembodiment of a VRB 100 in accordance with the principles of theinvention. In this illustrative embodiment, a symmetric VRB 100 mayinclude a plurality of hand positions 315, which indicate one set ofresistance ranges in relationship to the fulcrum point. An asymmetricVRB 100, it may include a plurality of hand positions 310, whichindicate two sets or multiple levels of resistance ranges inrelationship to the fulcrum point and rotated orientation.

FIG. 4 illustrates a view of an exemplary embodiment 400 of an equipmentincorporating a VRB 100 in accordance with the principles of theinvention. In this illustrative embodiment, a VRB 100 can be insertedinto a plurality of insertion points or rod holders 420. The exerciseequipment includes a plurality of tracks 410, a plurality of rod holders420, a bench 430 that may be positioned substantially perpendicular tothe plurality of tracks 410 or at an incline angle with respect to theplurality of tracks.

The tracks may be mechanically fixed in vertical or horizontal planes orany combination to maximize rod bend, defined as mechanical work orexercise matched to human proportion or otherwise described as theergonomic interface.

FIG. 5 illustrates a view of an exemplary embodiment of an equipment 500in accordance with the principles of the invention. In this illustrativeembodiment, a VRB 100 can be inserted into a plurality of insertionpoints. The equipment 510 includes at least one track, which can be wallor floor mounted. Each of the at least one tracks includes rod holders520. In addition, the walls 530 of the rod holder may be perpendicularor conical with respect to the track 510. Rod holders 520 may furtherinclude a stabilizing foot 540 in contact with track 510.

The anchored resistance rod (VRB) generates increased or decreasedresistance by anchoring the rod at its base and therefore the user cancontrol the degree of rod bend.

This allows the rod to be used as a dynamic resistance beam for usefulexercise. The beam resistance is dependent upon the degree of bend andhand position.

FIG. 6 illustrates a view of an exemplary equipment 600 in accordancewith the principles of the invention. In this illustrative embodiment, aVRB 100 can be inserted into selected ones of a plurality of insertionpoints 610. In this exemplary embodiment, a plurality of perpendicularrod holders or insertion points 610, similar to those described withregard to FIG. 5, may be incorporated onto a handheld transportablefolding workout platform 600.

FIG. 7 illustrates a view of an exemplary equipment 700 in accordancewith the principles of the invention. In this illustrative embodiment, aVRB 100 held in place by foam or other lightweight material 710 within ahollow shaft 720. The position and/or orientation of the VRB 100 withinthe hollow shaft 720 may determine the stiffness and/or flexibility ofthe hollow shaft. That is, in the case, a type I VRB 100 is incorporatedinto the hollow shaft 720, the length of the type I VRB 100 maydetermine the stiffness of the hollow shaft. On the other hand, if atype II VRB 100 is incorporated into the hollow shaft, then theorientation of the splines to a proposed bending force determines thestiffness and/or flexibility of the hollow shaft 720.

The resistance beam upon manual customized selected rotation impartsgreater flexibility or rigidity to the hockey stick by the user, tocustomize the equipment's response to the user's athletic ability.

Additionally, another method of imparting greater flexibility orrigidity is to raise or lower the resistance beam within the shaft tochange the fulcrum or kick point of the stick.

FIG. 8 illustrates a view of an exemplary embodiment of an equipment 800in accordance with the principles of the invention. In this illustrativeembodiment, an internal VRB 100 is held in position within a hollowshaft by a lightweight material 815, as described with regard to FIG. 7.In addition, one end of the VRB 100 is positioned on a bushing 810comprising a flexible material such that it may compress or expand aspressure is applied to the bushing 810. In one aspect of the invention,the bushing may be made of an elastometric material such as a polymer,foam, urethane, rubber, or so the similar material that may becompressed and returned to an original state when the compressive forceis removed. At a second end, the VRB 100 is attached to a means 820 forraising or lowering the VRB within the hollow shaft. The means 820 maybe a worm gear type mechanism that raises or lowers the VRB 100, tocreate a variable shaft flex. The VRB 100 may be lowered by compressingthe bushing material 810 and raised by removing the compression pressurefrom the bushing material 810. Although the means for positioning theVRB 100 is shown as a worm gear that may be turned by an Allen key, itwould be recognized that other types of rotating means may beincorporated without altering the scope of the invention. For example,the means for adjustment to alter the position of the VRB 100 may be ascrew thread position along the outside of the hollow shaft and theturning of a cap on the top of the hollow shaft may lower or raise theVRB 100.

In the illustrated embodiment of the invention shown herein, a VRB 100rod is centrally raised or lowered within the hollow shaft to increaseor decrease flexibility or rigidity of the golf shaft, thereby shiftingthe kick point or maximum point of flexure up or down the hollow sectionof the shaft.

Thus, the player or user may select a shaft flex or rigidity range thatmatches the player's specific swing type, strength and ability.

The 360 degree symmetrical geometry provides a solution for anadjustable golf club and would be fully compliant with the existing USGA(United States Golf Association) rules of golf.

FIG. 9 illustrates an exemplary ski sports equipment configuration 900with an adjustable resistance beam VRB 100 that imparts a resistancerange along a length of the body of the ski in accordance with theprinciples of the invention.

The adjustable resistance beam VRB 100 imparts a range of performancecharacteristics into the ski to match the skier's skill and terrainrequirements.

In one application of the VRB described herein, downhill skiing requiresa very rigid ski. By adjusting the resistance beam to the highestrigidity setting, the ski will become more rigid with a faster dynamicresponse when carving turns. A more rigid ski is desirable for icyconditions due to the ability to hold its shape and maintain maximumedge contact with the snow and ice surface.

In another application, mogul skiing over bumps requires a flexible ski.By adjusting the resistance beam to its most flexible setting, the skiwill become more conformal to bumps and bend and flex over them.

Thus a terrain adaptable ski is created from a mechanically joinedadjustable resistance beam.

The means for positioning the VRB 100 may be similar to that describedwith regard to FIG. 8.

FIG. 10A illustrates a view of an exemplary embodiment of a lawnequipment 1000 in accordance with the principles of the invention. Inthis illustrative embodiment, tines are individual VRBs 100, and can besimultaneously adjusted to create equal flex in each tine.

FIG. 10B illustrates a bottom view of an exemplary embodiment of a lawnequipment 1000 in accordance with the principles of the invention. Inthis illustrative embodiment, the tines VRB 100 may be simultaneouslyrotated equally to create variable flex.

The rotated tines are locked into an incremental range of resistancepositions that are either the most flexible for raking leaves or themost rigid to raking gravel. At the end of each tine is an ellipse thatacts a hook dependent upon its rotated orientation.

FIG. 11 illustrates a view of an exemplary embodiment of an equipment1100 in accordance with the principles of the invention. In thisillustrative embodiment, internal VRBs 100 are adjusted to create avariable flex. Equipment 1100, which represents an athletic shoe,includes a rubber shoe sole 1115. The athletic shoe 1100 furtherincludes a heel fulcrum 1125 and a toe fulcrum 1130. Between the heelfulcrum 1125 and the toe fulcrum 1130 is an internal cavity 1110. Withincavity 1110 is positioned at least one VRB 100. The VRB 100 includesanti-rollover collars 1110 a, which prevent the VRB beam deflection ordistortion and are spaced along the VRB 100. The at least one VRB 100located within the internal cavity 1110 may be adjusted by an adjustmentmeans 1120 that rotates the VRB within cavity 1100. The VRB 100 isfurther locked in position. The means for positioning the VRB may besimilar to that described with regard to FIG. 8.

The transmission of the shoe wearer's strength (power) from their legsinto the ground is directly affected by the sole stiffness of the shoe.By employing an adjustable resistance beam as described herein, runnersmay gain more leverage and, thus more speed, by using a responsive shoesole customized to their specific requirements.

An adjustable pair of resistance beams within the shoe sole may beinsertable, insert molded or structurally connected to the shoe sole inlateral and/or longitudinal positions within the sole and are rotatableto a fixed and mechanically locked position to effect custom flexuralresistance range that matches the wearer's optimum performancerequirement.

Thus, the resistance beam technology described herein is designed to bea dynamic, adjustable, in-sole suspension system that can absorb theweight of the wearer and release it per each step.

In accordance with the principles of the invention, a VRB orthoticsupport system to provide selectable arch support may be incorporated asin-sole orthotic device to provide adjustable and dynamic geometry tosupport the structures and or additional quadrant zones of the foot isdisclosed.

The orthotic arch platform supports the zones of the foot from the VRBsdynamic, reactive, selective resistance to loading, resulting in dynamicsuspension per one or more zones, e.g. mid arch, et al., providingvertical lift from the VRB cantilever to maintain physiologic supportwith bio-mechanic balance and comfort.

The orthotic platform effectively maps the differential loading pointswith resistance or suspension levels of the foot per zone andcompensates with reactive support that can be selectively increased ordecreased to match any podiatry foot condition or performanceenhancement for sports or extreme physical activity, e.g. military,where the wearer's loads are often variable.

The orthotic platform acts as a type of selectable leaf springsuspension or in multiple zones, a cat's paw or multi-zone cantilever inthe shape of an ‘X’ to combine variable resistance settings and/orheight geometry from VRB dynamic suspension. This reactive systemvertically ‘reacts’ or lifts body weight loads placed upon its surfaceper zone, to maintain and respond to proportionate bio-mechanical footbalance loading and therefore comfort or pain relief, with athleticenhancement.

In conjunction with a ‘dedicated mid arch zone or individual VRB archstructure is integrated with the footwear cat's paw or X platform withup to 4 VRBs to create a completely multi-zone adjustable anddynamically supportive orthotic foot device. The orthotic device maytake a product form of a stand-alone shoe insert, integrated (i.e.,overloaded or insert molded into the sole of the shoe or boot) and/or bepartially captured or molded into the shoe or boot sole.

The reactive, dynamic and selective support levels of the orthotic zoneswith VRBs are a function of the VRBs inclination angle, length andwidth, material tensile strength or fulcrum position in relation to theunderside of the foot loading, and/or extension from within shoe sole.Additionally, selectable resistance in conjunction with differentvariable orthotic shell geometries provides a wider prescriptiveresistance range to match heavier bodyweights, severe in-field operatingrequirements, and/or corrective foot conditions.

In accordance with the principles of the invention, at least one VRB isattached, typically inclined, to the underside of the mid arch to impartdynamic suspension or to reactively support the compressive loads of thefoot. The orthotic platform and mid arch flex with the VRB so as toprovide responsive dynamic and zoned suspension support with conformalgeometry mapped to foot loading. The arch platform maximizes surfacearea by distributing loads over a greater area, with a responsive anddynamic conformal surface to support the loads in real time andproportion.

Additionally, by extending the length of one or more VRBs, the VRBsbecome extendable into one or more of the 4 quadrant zones of the shoeto impart selectable dynamic responsive support to the bio-mechanicloads placed upon the arch platform. A single VRB may act as a dualcantilever to support two different support zones or structures, e.g. aVRB may support the foot arch and rearward heel zone by one or morefulcrums or ‘stops’ placed along the VRB length to impart calculated,and therefore, selectable cantilevered suspension to dual zones.

In accordance with the principles of the invention, a VRB acting as acantilever provides dynamic arch support over a selectable range tomatch a wearer's biomechanics corrective requirement with comfort. If aprescriptive setting is initially too stiff, hard or uncomfortable forthe wearer, a lower VRB setting may be used to allow the wearer‘break-in’ time for re-alignment processes of the foot structures tocorrect, thus maximizing comfort with prescriptive benefit and enhancedcustomized athletic performance.

Additionally, one or more VRBs are extendable into each of the 4quadrant zones of the shoe to impart selectable dynamic responsivesupport to reduce the ‘break-in’ period for the shoe, increasingcomfort.

The VRB selectable support range provides for a range of loads thatcontrols the supportive flexure of an orthotic shell or footwear,specifically the mid arch geometry. This in turn provides reactive archgeometry that will flex in proportion to the VRB setting and thereforeimpart dynamic arch support proportional to loading.

In accordance with the principles of the invention, the zone loadingand/or mid arch loading and, therefore, the VRB loading curve[s] or thequantified in vertical lift force in pounds (Lbs) of response to weightloads placed on the VRB extending into each shoe zone or mid arch shellstructure are bell curved. The bio-mechanic effect of a cantileverabsorbing and releasing proportional loads in a Bell Curve results inmaximal comfort throughout the entire gait cycle and at each VRBresistance setting. This is an important and intended integral designengineered bio-mechanic effect of using cantilevers to dynamicallysupport body joints, e.g. foot et al., to provide a smooth bell curveresponse for maximal comfort throughout the flexural VRB range.

The mechanical resistance or support of the VRB can be design engineeredto correspond to any required loading curve, e.g. rehabilitative, postsurgical, prophylactic, extreme sports, performance enhancement and themilitary for high rucksack equipment loading in pounds (Lbs). Equally,more robust VRBs can be easily incorporated into an orthotic device tosupport the arch from heavy equipment loads carried via rucksack, e.g.100 Lbs or more.

In accordance with the principles of the invention, responsive,proportioned and dynamic zone(s) of support create a self-levellingstructural orthotic shell for the foot, enhancing the wearer's athleticability or dynamically correcting imbalances. This provides a real time,proportionately customizing orthotic to support the load requirements ofthe foot.

The greater the load upon the foot, the greater VRB vertical suspensionor resistance to compression by immediate vertical (dynamic height)lifting support. The self-leveling platform matches the dynamic loadsplaced upon the zones of the foot/arch in proportion to load. The VRBcompression and release of load results in proportional, verticallifting support to the arch of the foot or per zone.

The arch and zones are supported by one or more VRBs that dynamicallyreact in direct proportion to the loads placed upon them. The orthoticshell is ‘pre-loaded’ or at a higher height geometry to allow the footto engage and proportionally compress and engage the VRB zones (midarch, et al.) of support levels to ensure a mapping of supportedstructure with cantilevered resistance ranges. Each individual zone isselectable with customizable suspension range.

In accordance with the principles of the invention, the VRB technology,disclosed, herein, dynamically supports the loads of the mid arch, tostabilize pronation and supination mechanics, by providing customizable,dynamic, cantilever based suspension ranges with one VRB under the midarch area or up to four or more cantilevered VRB zones of selectableresistance, to further support and correct bio-mechanical imbalances ofthe foot.

The orthotic platform, disclosed herein, combines dynamic verticalmid-arch support with variable geometry through a flexible orthoticshell that adjusts to each height and resistance or suspension settingfrom a single VRB or up to four or more zones with selectable resistancecantilever. The shell acts as a dynamic suspension surface to verticallyreact or lift body weight loads placed upon its surface and to maintainproportionate bio-mechanical foot balance and therefore comfort and painrelief.

The mid-arch support variable geometry levels are a function of VRBinclination or other mechanical methods of providing selectable heightto adjust the mid arch position of the orthotic blade, to lift orsupport the bodyweight proportionate to foot loading. Additionally,selectable resistance in conjunction with variable shell geometry toprovide prescriptive resistance ranges to match bodyweight andcorrective foot conditions.

The orthotic system disclosed herein provides a lightweight, variableresistance of support to proportionally counter act body weight placedupon the foot to dynamically maintain bio-mechanical balance.

The unique cantilevers configuration of variable resistance beamsproduces a significant range of selectable performance resistance levelsto match a body weight or specifically foot condition.

Additionally, the orthotic platform disclosed, herein, providesselectable flex that represents an integrated anti-pronation/supinationmechanisms that responds to increasing medial loads by dynamicstiffening in proportioned response to body weight loading. The VRBresistance to compression or suspension is designed to be selectivelyincreased or decreased prescriptively to maximize therapeutic benefitwith comfort.

The cantilever system disclosed herein provides selectable incrementalresistance to pronation/supination “on demand” to meet the needs of awide range of patient foot imbalances, comfort requirements and podiatryconditions.

The adjustable or selective VRB orthotic technology enhances the user'sbio-mechanical performance and therefore comfort by offering thePodiatrist a prescriptive incremental range of selectable resistances,per each customized zone of the foot to treat each patient'sbio-mechanical, comfort and or specific sport performance requirements.

FIG. 13A illustrates a perspective view of an exemplary embodiment of anorthotic 1300 including a VRB suspension support system 1303 inaccordance with the principles of the invention.

As shown in FIG. 13A, the VRB orthotic variable resistance andsuspension system 1303 includes a VRB 100 (hereinafter referred to as1310), which is inserted through heel 1340 and extends to the mid-archsection 1350, positioned below an insole or force plate or platform 1305of footwear 1300. As shown insole or force plate or platform 1305includes an upper surface 1320 and a lower surface 1325.

Further illustrated is heel section 1340 having a flat surface 1345 andforce plate 1305 having a front section 1360. Flat surface 1345 andfront section 1360 rest on a same plane.

As will be discussed, the VRB 1310 comprises a generally elongatedcylindrical beam or bar that includes a major axis greater than a minoraxis. The orientation of the VRB 1310 with respect to the mid-archsection determines a degree of flexibility (or rigidity) that supports afoot load impacting or applied to the mid-arch section 1350. The VRB1310 may be inserted and oriented at different degrees of orientationwith regard to its major axis in order to adjust the degree offlexibility (or rigidity) of mid-arch section 1350. The degree ofrotated orientation imparts a selectable resistance range per incrementof rotation. For example, using an elliptical VRB, as is described withregard to FIG. 22D, in a 90° vertical or long axis position, the VRB1310 is most rigid, while in the 0° horizontal (flat) position, VRB 1310is most flexible. VRB 1310 operates as a cantilever to dynamicallysupport and suspend the mid arch section 1350 with selectableresistance. In one aspect of the invention for selecting resistance,tensile strength of the material comprising VRB 1310 may be selected toaffect flex performance, e.g., 1,000, 5,000, 10,000 or higher PSIPolymer tensile modulus.

As shown, VRB 1310 extends at an angle from heel section 1340 tomid-arch section 1350 to form a cantilever upon which mid-arch section1350 rests. As a load is applied to the mid-arch section 1350, themid-arch section 1350 engages and depresses VRB 1310. Based on theorientation of VRB 1310 with respect to mid-arch section 1350, VRB 1310applies different levels of resistance to the force or load applied tomid-arch section 1350.

Each VRB selected resistance or suspension level provides and imparts azone of tailored bio-mechanical support to dynamically correctimbalances, eg. Pronation/Supination/Posting of the foot, byredistributing ground reaction forces, as well as realigning foot jointswhile standing, walking or running

The biomechanics from each zone reacts by providing a smooth bell curveof support to dynamically and proportionally correct foot imbalance[s]to enhance foot performance per specific activity, e.g., weightdynamics, energy return from loading and unloading, cornering,sprinting, running, walking or to ease of locomotion.

FIG. 13B illustrates a perspective, underview, of an orthotic 1300including a VRB orthotic support system 1303 in accordance with theprinciples of the invention.

As illustrated, VRB 1310 extends from heel section 1340 to mid-archsection 1350, wherein VRB 1310 terminates in pocket 1510. Pocket 1510captures a free end of VRB 1310, while allowing the VRB 1310 to rotatefrom a minimum resistive position to a maximum resistive position. AsVRB 1310 rotates from a minimum resistive position to a maximumresistive position, the height of mid-section 1350 is changed, whilesimultaneously altering the degree of support or rigidity applied to themid-section 1350.

Also illustrated is an exemplary selection or adjustment mechanism 1520incorporated into heel section 1340. Adjustment mechanism 1520 enables auser to adjust VRB 1310 from a first (e.g. minimum resistive) positionto a second (e.g., maximum resistive) position. In this exemplaryembodiment, the adjustment mechanism 1520 represents a socket typeadjustment, which will be described in further detail.

Although the VRB orthotic variable resistance and suspension system 1303discussed herein is shown in FIG. 13A as being beneath the force plateor platform 1305 of footwear 1300, it would be appreciated that the VRBorthotic variable resistance system 1303 may be included within thefootwear 1300 wherein force plate 1305 comprises one layer in contactwith a user's foot (i.e., upper surface 1320) and a second lower layer(not shown) in contact with the external environment. This second lowerlayer connects front surface 1360 and heel section 1340 in a mannersimilar to that of a sneaker, for example.

FIGS. 14A-14C illustrate different degrees of support for a mid-archsection 1350 based on an orientation of VRB 1310 with regard to a samelevel of force (F) applied to the mid-arch section 1350.

FIG. 14A illustrates a degree of support for mid-arch section 1350 whenVRB 1310 is in a minimum resistive position. In this case, VRB 1310provides a minimum resistance to force F applied to mid-arch section1350, such that VRB 1310 may have a maximum deviation from an angle ofinclination 1410 of VRB 1310 measured with respect to heel surface 1345.

FIG. 14B illustrates a degree of support for mid-arch section 1350 whenVRB 1310 is in a position between a minimum resistive position and amaximum resistive position. In this case, VRB 1310 provides a mid-levelresistance to force F applied to mid-arch section 1350, such that VRB1310 may have a mid-range deviation from an angle of inclination 1410 ofVRB 1310 measured with respect to heel surface 1345.

FIG. 14C illustrates a degree of support for mid-arch section 1350 whenVRB 1310 is in a maximum resistive position. In this case, VRB 1310provides a maximum resistance to force F applied to mid-arch section1350, such that VRB 1310 has a minimum deviation from an angle ofinclination 1410 of VRB 1310 measured with respect to heel surface 1345.

As shown in FIGS. 14A-14C, a height of mid-arch section 1350 may bealtered based on the orientation of VRB 1310 with respect to themid-arch section 1350 and heel section 1340.

In another aspect of the invention, a height 1430 of mid-arch section1350 may be determined based the angle of inclination 1410 of VRB 1310with respect to surface 1345. In a preferred embodiment, the angle ofinclination 1410 of VRB 1310 with respect to a surface 1345 is in therange of 1 degree to 45 degrees. As would be recognized, the angle ofinclination of VRB 1310 contributes to the height of mid-arch section1350 and to the resistance of VRB 1310 to a force applied to mid-archsection 1350.

FIG. 15 illustrates a perspective view of an exemplary second embodimentof a VRB orthotic variable resistance and suspension system 1303 inaccordance with the principles of the invention.

In this illustrated embodiment, two VRBs 1310 are shown supporting anoptional attachment plate 1610 under force plate 1305. In thisillustrated embodiment, two VRBs 1310 are positioned on a left side anda right side of attachment plate 1610. Application of multiple VRBs 1310provides for symmetric or asymmetric support of a force applied tomid-section arch 1350. Although two VRBs 1310 are shown, it would beappreciated that additional VRBs 1310, extending toward the front offorce plate 1305 may be incorporated without altering the scope of theinvention. While attachment plate 1610 provides a base onto whichpockets 1510 may be attached, it would be recognized that pockets 1510may be directly attached to, or conformally configured into, force plateor platform 1305, in a manner shown in FIG. 13A, for example.

Also shown are corresponding entry points 1530 that allow access toadjustment mechanisms 1520, which provide individual control of acorresponding VRB 1310. In this illustrative example, adjustmentmechanism 1520 alters the orientation of VRB 1310 with respect tomid-arch section 1350 through the rotation of a gear assembly, as willbe discussed with regard to FIG. 17A-FIG. 17C, for example.

In the configuration shown, support provided by the VRB 1310 under themid-arch section 1350 may be adjusted to be firmer on one side thansupport provided by the VRB 1310 on the other side to provide acustomized level of support.

Also illustrated is heel plate 1560 that may be incorporated into VRBorthotic variable resistance and suspension system 1303. Heel plate 1560provides additional support for heel section 1340 and an angle ofinclination of VRB 1310.

FIG. 16 illustrates a planar view of an aspect of exemplary embodimentof a VRB orthotic configuration 1303 in accordance with the principlesof the invention.

As illustrated, optional attachment plate 1610 extends from the heelportion 1340 to the mid-arch section 1350 of force plate or platform1305. Attachment plate 1610, incorporated into sole-plate 1305 providesa surface over which a load or force applied to mid-arch section 1350may be distributed. Attachment plate 1610 includes a heel plate section1620 that is attached to sole plate 1305 in the heel section 1340. Alsoshown is a mid-arch section 1630 of plate 1610, which includes pocket1510. Plate 1610 may be attached to sole plate 1305 using an adhesive,screws or rivets.

As would be recognized FIG. 16 illustrates a configuration applicable toa right side orthotic 1300 as VRB 1310 is positioned on a left side oforthotic 1300 so as to be positioned below the corresponding arch. Aswould be appreciated, the orientation of plate 1610 and VRB 1310 may bealtered to be positioned on a right side of orthotic 1300, so as to beapplicable to a left side orthotic. Incorporation of the VRB orthoticvariable resistance and suspension system 1303 in a right side orthoticand a left side orthotic is contemplated and considered within the scopeof the invention claimed.

Further illustrated is VRB 1310 extending from pocket 1510 to plate1620, which incorporates another aspect of an adjustment mechanism 1520in accordance with the principles of the invention. In this illustrativeexample, adjustment mechanism 1520 alters the orientation of VRB 1310with respect to mid-arch section 1350 through the rotation of a gearassembly, as will be discussed with regard to FIG. 18A-FIG. 18F.

In one aspect of the invention, plate 1610 may be conformed to mid-archsection 1350 to provide a customized support for mid-arch section 1350.As would be appreciated, plate 1610 may be flat, conformed and/orcustomized without altering the scope of the invention.

As is further shown, VRB 1310 may be contained within a substantiallycircular housing, sleeve or sheathing 1312. Housing 1312 enables VRB1310 to rotate substantially uniformly from a minimum resistanceposition to a maximum resistance (or support) position. In one aspect ofthe invention, the VRB 1310 may rotate within sheathing 1312, whereinsheathing 1312 is fixed. In another aspect of the invention, VRB 1310may be attached to sheathing 1312 and as sheathing 1312 rotates, thecontained VRB 1310 rotates.

As will be discussed with regard to FIG. 22A-FIG. 22F, VRB 1310 maypossess an elongated shape having a major axis greater than a minoraxis, which is substantially perpendicular to the major axis.

FIG. 17A-FIG. 17C illustrate end views of VRB 1310 including aspects ofa first embodiment of an adjustment mechanism for altering theorientation of the VRB 1310.

FIG. 17A illustrates an example of an end of VRB 1310, which isaccessible through heel section 1340, for example, that includes threecircular cut-outs or indentations 1380 formed in a triangular pattern.Insertion of a tool (e.g., a screw driver) matching the indentationpattern 1380 allows for the rotation of VRB 1310.

Although indentations 1380 are shown in a triangular pattern, it wouldbe recognized that the indentations 1380 may be arranged in any patternthat allows rotation of VRB 1310 to change the orientation of its majoraxis with respect to heel surface 1345.

FIG. 17B illustrates a second example of an end of VRB 1310 thatincludes a diamond shaped indentation 1385. In this case insertion of atool (e.g., a screw driver) matching the diamond shaped indentationpattern 1385 allows for the rotation of VRB 1310 to change theorientation of its major axis with respect to heel surface 1345.

FIG. 17C illustrates a third example of an end of VRB 1310 that includesa Philips (or cross) pattern. In this case Insertion of a tool (e.g., ascrew driver) matching the Philips (or cross) indentation pattern 1390that allows for the rotation of VRB 1310 to change the orientation ofits major axis with respect to heel surface 1345.

FIG. 18A-FIG. 18F illustrate exemplary aspects of a second exemplaryembodiment of an adjustment mechanism in accordance with the principlesof the invention.

FIG. 18A illustrates an exemplary adjustment mechanism represented by aworm gear 1830, which engages a gear 1815 that is incorporated on asubstantially circular gear head 1810 to which VRB 1310 is attached.Worm gear 1830 may include an adjustment means (such as an indentation1860, which may capture an Allen key, Torx key, a Philips tip, forexample, as shown in FIG. 17A-FIG. 17C). Insertion of the Allen key intoindentation 1860 and rotation of Allen key causes rotation of worm gear1830. As worm gear 1830 rotates, the rotation of worm gear 1830 istransferred to the gear 1815 of head 1810 causing the rotation of VRB1310.

FIG. 18A further illustrates a locking plate 1820. Locking plate 1820retains worm gear 1830 (and consequentially VRB 1310) in a lockedposition, as will be discussed.

As would be appreciated as VRB 1310 rotates from a minimum resistanceposition, corresponding to minor axis position, to a maximum resistanceposition, corresponding to major axis position, support to mid-arch 1350increases from a minimum to a maximum.

FIG. 18B illustrates a top view of worm gear assembly 1850 includingworm gear 1830 and locking plate 1820. Further illustrated is screw(e.g. a set screw) 1825 that alters the position of locking plate 1820with respect to worm gear 1830.

In one aspect of the invention, as shown in FIG. 18B, assembly 1850includes a threaded opening 1861, through which passes set screw 1825 toengage locking plate 1820. As set screw 1825 is rotated in a firstdirection, locking plate 1820 is moved toward worm gear 1830. Lockingplate 1820 further includes a toothed surface opposite screw threads1835 of worm gear 1830. As locking plate 1820 advances towards worm gear1830, the toothed surface of plate 1820 engages screw threads 1835 ofworm gear 1830. In this position, worm gear 1830 is locked in position.Thus, the position of the VRB 1310 is fixed at that position to whichVRB 1310 has been rotated by the rotation of worm gear 1830.

In another aspect of the invention shown in FIG. 18C, as screw 1825 isrotated in an opposite direction, the toothed surface of locking plate1820 is withdrawn from screw threads 1835 and worm gear 1830 is free torotate. In this manner, locking plate 1820 moves inward or outward alongscrew 1825 as screw 1825 is rotated. The position of locking plate 1820may be altered by the insertion of an adjusting means, such as an AllenKey, a Philips screwdriver, etc., in screw hole 1861 to engage screw1825.

FIG. 18D illustrates a planar view of exemplary embodiment of the wormgear assembly 1850 in accordance with the principles of the invention.In this exemplary embodiment, locking plate 1820 engages screw threads1835 of worm gear 1830.

Also illustrated is gear head 1810 engaging screw threads 1835. Gearhead 1810 may be attached to VRB 1310, which enables VRB 1310 to rotatewithin sheathing or sleeve 1312. Alternatively, gear head 1810 may beattached to sheathing 1312 to allow rotation of VRB 1310.

FIG. 18E illustrates a planar view of orthotic 1300 including forceplate 1305 incorporating the gear assembly 1850 shown in FIG. 18A-FIG.18D. Assembly 1850 includes gear 1830, which engages gear head 1810attached to VRB 1310. VRB 1310 is captured in pocket 1510, as previouslydescribed.

Further illustrated is a conventional Philips tip screw driver 1890 thatmay be used to rotate gear 1830 by insertion of the Philips tip intoindentation 1860, which is shaped in a manner similar to that shown inFIG. 17C.

Although a conventional Philips tip screw driver 1890 is illustrated, itwould be appreciated that indentation 1860 may comprise a proprietaryshape requiring a corresponding proprietary tip similar to those shownwith regard to FIG. 17A-FIG. 17B.

FIG. 18F illustrates a side view of orthotic 1300 including force plate1305 wherein indentation 1860 is shown having a cross shape that engagesthe tip of Philips screw driver 1890.

As previously discussed, as gear 1830 is rotated, VRB 1310 is rotatedthrough the engagement of gear head 1810 with gear 1830.

FIG. 19A-FIG. 19D illustrate aspects of a third exemplary adjustmentmechanism for controlling rotation of a VRB utilized in the orthotic1300 shown in FIG. 13A and FIG. 13B, for example.

FIG. 19A illustrates a perspective view 1900 of a third exemplaryconfiguration of a control or adjustment means in accordance with theprinciples of the invention.

In this exemplary configuration, referred to herein after as“spline/socket”, a manual, geared, mechanism selectively rotates VRB1310 in controlled increments ranging from 0° to 90° whilesimultaneously controlling torque.

As shown, the socket/spline 1900 provides an adjustable locking systemthat secures a VRB 1310 from rotation and therefore mechanicallymaintains a constant resistance or suspension.

VRB 1310 further includes a fork or tongue 1910 that is insertable intospline 1920. Spline 1920 is a substantially round, solid, rod includingtongue or fork 1925. Tongue or fork 1925 engages (and matches) tongue orfork 1910 of VRB 1310.

Also shown is socket 1930 into which spline 1920 is inserted. Socket1930 contains fork 1925 and tongue 1910 in a manner such that as spline1920 is rotated, VRB 1310 is similarly rotated.

At a proximal end of socket 1930 is shown grooves 1935 and splineelements 1945 formed between adjacent ones of grooves 1935. In oneaspect of the invention, the spacing of spline elements 1945 (grooves1935), provides for a desired locking rotation. For example, 16 splineelements 1945 provide for 22.5° of incremental VRB 1310 rotation.(360°/16=22.5°).

In accordance with the principles of the invention, VRB 1310 plus spline1920 form an adjustable assembly, wherein the spline element 1920 may bepulled out by grasping spline head 1940, rotating the spline element1920 and re-inserting the spline 1920 into socket 1930, to provide ahigher or lower resistance or suspension level. This level of resistanceis dependent upon the rotation VRB 1310.

Also illustrated is faceplate 750. Faceplate 1950 includes an indicia ofthe degree of rotation of VRB 1310.

As would be appreciated, tongues or forks 1925 and 1910 are sized sothat they remain engaged, even when spline 1920 is pulled out, turnedand re-inserted into socket 1930.

FIG. 19B illustrates a perspective view of spline 1920. In thisillustrative embodiment, spline 1920 is a substantially cylindrical rodincluding at a first end fork 1925 and a spline head 1940 on a secondend. Further illustrated are spline elements 1945 positioned about acircumference of spline 1920 between adjacent ones of grooves 1935.

As shown, a length of fork 1925 is sufficiently greater than a length ofspline elements 1945 in order to prevent spline 1920 from disengagingVRB 1310 (not shown) when spline 1920 is pulled from socket 1930

FIG. 19C illustrates a perspective view of a spline element 1945 ofspline 1920 engaging grooves 1932 of socket 1930. In this illustrativeexample, socket 1930 includes a plurality of grooves 1932 and splineelements 1934 between adjacent ones of grooves 1932. Grooves 1932 andspline elements 1934 of socket 1930 match in number and width withspline element 1945 and grooves 1935.

As discussed, spline 1920 may be withdrawn from socket 1930, rotated andreinserted into socket 1930. The rotated and reinserted spline 1920alters the position of the VRB 1310 (not shown) such that a differentlevel of rigidity of VRB 1310 may be achieved (see FIG. 13A-FIG. 13C).The engagement of spline elements 1945 with grooves 1932 lock and retainVRB 1310 (not shown) in a desired position.

FIG. 19D illustrates a perspective view of a control mechanism 1900illustrating VRB 1310 engaging fork 1925 in spline 1920 in accordancewith the principles of the invention.

In this illustrative embodiment, VRB 1310, which is shown having arectangular cross-section, includes tongue 1910 that may be insertinginto fork 1925 in order to provide a secure connection between tongue1910 and fork 1925, as previously discussed.

Further illustrated is retaining ring 1970. Retaining ring 1970represents a spring loaded mechanism that enables spline head 1940 to bewithdrawn from socket 1930 by pushing spline head 1940 into socket 1930.The act of pushing spline head 1940 into socket 1930 disengagesretaining ring 1970 and the spring loaded mechanism forces spline head1940 to withdraw from socket 1930. In one aspect of the invention,retaining ring 1970 may be constructed of a spring-able material andshaped to operate as the spring mechanism.

Further illustrated are pins 1980, which when inserted into holes 1985provide a secure connection between fork 1925 and tongue 1910.

As would be appreciated holes 1985 may be elongated in order to allowspline head 1940 to be withdrawn from socket 1930 a limited distance. Inthis case, spline head 1920 may not be totally withdrawn from socket1930 (not shown) even if spline head 1940 is inadvertently pushed in.

FIG. 20A illustrates a perspective view of an exemplary variableresistance and suspension system 1303, similar to that shown in FIG.13A. In this illustrative embodiment, the VRB configuration includes anadjustment mechanism similar to that shown in FIG. 19A, wherein the VRB1310 may be rotated in discrete intervals. It would, however, beappreciated, that the adjustment mechanism shown in FIG. 17A-FIG. 17C orFIG. 18A-FIG. 18F may similarly be utilized without altering the scopeof the invention.

As shown in the enlarged section of FIG. 20A, bio-sensor 2030 may beincorporated onto the force plate 1305 of orthotic 1300. Incorporationof bio-sensor 2030 provides for a prognostic and injury avoidancecapability to measure a mechanical deflection of dynamic loads beingexerted on a body joint or structure. This is principally achievedthrough the monitoring of the flexing shape of a VRB (VariableResistance Beam) or multiple VRBs as loads are dynamically applied,quantified and recorded with the wearer notified of loading conditionsthat would exceed the joints physical ability sustain normal operationwithout damage, e.g. repetitive strain. Thus, measurement of dynamicjoint loading over time provides a real time health monitoring andpredictive system to prevent or treat injury.

A few examples of physical sensors 2030 to measure and quantify jointstress, strain loading cycles, and/or changing suspension supportrequirements are Thin Films, Wheatstone Bridges (metal foil sensorstructures), potentiometers, temperature gauges, pressure gauges, foils,piezo-resistors, semiconductors, nano-particulates, conductivenanolayers, silver nanowire, Graphene, e.g. graphene imbued rubberbands: flexible, low-cost body sensors, such as nanoelectromechanicaldevices, piezoresistive devices, conductive electroplating, diffractiongrating, optical fiber, optical grid (Non-Intrusive Stress MeasurementSystem—NSMS), wire, micro tubes, miniature WiFi transmitters,accelerometers, load cells and or other means to detect VRB flexure ormovement of any kind.

Physical sensing of the application of a force or strain occurs when oneor more VRBs 1310 is deflected or flexed. As the physical shape of theVRB is deformed, an electrical resistance changes. Similarly othermeasurement quality(ies) or physical parameter(s), e.g. optical,physical location or acceleration, are similar effected.

For example, the Wheatstone bridge illustrates the concept of adifference measurement, which can be extremely accurate. Variations onthe Wheatstone bridge can be used to measure capacitance, inductance,impedance and other quantities to calculate total potential movementover time.

Although FIG. 20A illustrates the placement of bio-sensor 2030 on forceplate 1305, placement and locations of the bio-mechanic sensors 2030 maybe bonded onto or along the surface length of VRB 1310 into a sidechannel and/or internally through an interior diameter hole, bore and orextruded geometry to accept and hold the sensor. (see for example,element 2030′). FIG. 20B illustrates exemplary placement of sensors 2030on or within VRB 1310.

In another aspect a strain gauge may be incorporated in which advantageis taken of the physical property of electrical conductance and itsdependence on the conductor's geometry. For example, when an electricalconductor is stretched within the limits of its elasticity withoutpermanent deformation, the sensor will become narrower and longer. Thischanges or increases the electrical resistance along the sensors lengthor end to end. Silver nanowire is an excellent example of an electricalconductor with a 150% stretch limit while measuring conductivity withfidelity.

When measuring electrical resistance of a strain gauge bonded to a VRB1310, the amount of applied stress may be inferred. As an example,another typical strain gauge arranges a long, thin conductive strip in azig-zag pattern of parallel lines such that a small amount of stress inthe direction of the orientation of the parallel lines results in amultiplicatively larger strain measurement over the effective length ofthe conductor surfaces in the array of conductive lines—and hence amultiplicatively larger change in resistance—than would be observed witha single straight-line conductive wire.

Other methods of sensing VRB deflection range from temperature (kineticheating), piezo (milli-voltage generation), electromagnetic sensing,optical sensing (diffraction grating), to miniature WiFi signallingphysical location and or accelerometer chips.

As would be recognized one or more of the described sensors, herein, maybe incorporated into the illustrative sensor 2030 (or 2030′). Allsensors may directly wired and connected to a physical circuit. Or bymeans of a wireless signal to an embedded printed circuit board (PCB)with processing algorithm, battery and transmitter information regardingthe flex and/or stress detected may be processed (using one or morealgorithms) on the PCB and the results forwarded to a remote receiver(i.e., handheld or worn) to alert the wearer to potential injury orcurrent physical condition. Similarly, the measured parameters (i.e.,raw data) may be provided to a remote receiver for subsequentprocessing.

In another aspect of the invention, with the addition of accelerometermicrochips, e.g. similar to ones used in smartphones/tablets/watches orsuch devices, 360° X Y Z axial data is produced and therefore a moreinformative and prescriptive biomechanic measurements may be captured towarn of impending injury and inform the wearer whether the feet areincreasingly pronating or supinating mechanics.

An accelerometer chip interfaced with one or more biosensors 2030 mayprovide further prescriptively diagnose of the body joint condition,i.e. foot, by using quadrant data of the foot to compare and contrastbody weight loading (history) and changing weighting dynamics per zone.Specifically, this quadrant data of weight loading combined with anaccelerometer chip detecting movement in 360° X Y Z axes may determinewhether an injury or foot condition is worsening, progressing to injury,failure, as well as monitor and quantify podiatry foot conditions, e.g.heel posting.

This data would be central to the diagnosis, treatment and physicaltherapy. Measurement of the parameters associated with the application aforce to the variable resistance and suspension system 1303 shown inFIG. 13A, for example, may be customized and tailored to eachindividual's support requirement and notably reduce atrophy by allowingthe wearer degrees of movement.

FIG. 21 illustrates an exemplary configuration of a handheld device 2190communicating with one or more sensors 2030 (2030′) incorporated intothe variable resistance and suspension system 1303 shown in FIG. 13A,for example.

As would be appreciated communication between sensors 1530 (1530′) maybe through a short range communication protocol, such as BLUETOOTH, NFC,etc.

In one aspect of the invention, the VRB 1310 mechanical movement may becaptured by piezo, dynamo (polyphase AC/DC electric motor), hydraulic orother mechanism to capture and store mechanical energy from the VRBflexing or orthotic shell cyclical compression during walking. Thissystem may be used as a battery recharging system using a device capableof capturing mechanical movement and converting the mechanical movementinto electrical energy. For example, piezo-material or PvF2(PolyVinylidene Fluoride 2) may be incorporated into the VRB assembly tocreate a battery recharging system and/or a heel cushion to absorbbodyweight impacts via shock absorbing diaphragm. Additionally, part ofthe energy generated would be used to transmit the bio-sensor data to awearable device (2190, FIG. 21) to inform the wearer in real time of thecondition of their body joint condition, i.e. left or right foot.

In another aspect of the invention, the recharging system may also beconnected to and provide energy to drive a worm gear servo to change theVRB resistance setting to prescriptively support the body jointcondition in response to the bio-sensor data. This closed looped systemprovides a prescriptively corrective, rehabilitative, prophylactic orpreventative support system for a body joint or extremity, e.g. foot, byincreasing and/or decreasing the support imparted. The closed data loopsystem consists of a flexing VRB 1310 to biomechanically support a bodystructure or joint bonded to a Biosensor whose data stream is connectedto an ‘onboard PCB’ (printed circuit board). The biosensor data signalis received, transmitted and stored onto the PCB to produce an algorithmoutput. The closed data loop system is sustained by a mechanism tocontinually charge a battery and/or supply electricity to charge thesystem. An advanced version of this charging system could be employed toautomatically instruct a worm gear servo to change the VRB supportlevels (lower or higher) per biosensor diagnostic algorithm data stream.

In another aspect of the invention additional means of creating selfadjusting orthotic shell geometry may incorporate the use ofprogrammable smart materials, such as carbon fiber, nitinol wire mesh,smart, self-morphing filaments, e.g. wood, or composite materialsdesigned to become highly dynamic in form and function, specificallywhen a electric charge is applied or other shaping factors.

FIG. 22A-FIG. 22F illustrate cross-sectional views of exemplaryembodiments of a VRB in accordance with the principles of the invention.The VRBs, presented as resilient rods, beams or shafts, may be composedof solid, semi-solid or hollow construction in accordance withembodiment the principles of the invention. The VRB technology comprisesa major and minor axis, which produces variable resistances whenorientated in a direction of x, y, z plane or combination of planes in360 degrees of rotation, bending movement.

FIG. 22A represents a Type II I-Beam configuration 2210 that includesone of: a static outside and internal diameter geometry or combination,thereof. The Type II I-Beam cross section geometry produces proportionaladjustable resistance according to a rotated orientation creating arelationship between an orientation and a resistance.

FIG. 22B represents a Type III Dual I-Beam configuration 2215 thatincludes inner and outer I-Beam tubes with inner and/or outer geometryor combination thereof to create variable I-beam resistance.

FIG. 22C represents a Type IV Conical beam configuration 2220 thatincludes hollow, additive or subtractive wall geometry. Conical Beamcross section geometry produces proportional adjustable resistanceaccording to a rotated orientation.

FIG. 22D represents a Type V Ellipsoidal beam configuration 2225 thatmay be a solid, a semi-solid or a hollow beam with or without outsideand/or internal diameter geometry or a combination, thereof along itsmajor axis, thus, generating additional I-beam mechanics and/orsubtractive, e.g., conical hollow, geometry along its minor axis.Ellipsoidal beam with a major axis that is wider than the minor axiswith or without internal or external geometry along the major axis.

FIG. 22F represents a Type VII Rectangular beam configuration 2235 thatincludes two sides wider than the remaining two sides.

VRB 1310, which may be solid, semi-hollow or hollow, with or withoutgeometrically created I-beam effect (i.e., asymmetric geometry, spines)on the outside or interior diameter generates resistance depending onthe axis of orientation and/or a fulcrum position has been describedherein. A VRB 1310, with incorporated I-beam geometry on the outsidediameter, may allow for the dynamic adjustment of resistance of thedevice. An advantage of a device including VRBs described herein may becompact, lightweight and offer the ability to more easily and quicklychange a desired level of resistance than is typically found in unitsusing weights, rubber bands, bows or springs. By simple reposition orrotation of a VRB incorporated into the device, a desired selectablerange of resistance level may be achieved. The VRBs 1310 disclosed,herein, can provide resistance, depending on the orientation of thebeam, to a bending direction. In addition, an exemplary deviceincorporating the VRB technology may vary the resistance provided to theuser during rehabilitative exercise, without interrupting the exercisecycle. Additional beam resistance is achieved depending upon therelative orientation of the beam within a 180° degree hemisphere ofmovement relative to the user.

Hence, according to the principles of the invention, a progressivedynamic resistance may be achieved with a variation of the orientationof the beam or shaft shown herein.

In one aspect of the invention, rods with symmetrical cross sectionsvary their bending resistance by shortening and lengthening the arclength, from fulcrum to anchor point by hand position per indicia.

In another aspect of the invention, rods with asymmetrical crosssections may increase or decrease their bending resistance by rotationof the elongated orientation with respect to a bending force, whilemaintaining the same hand adjusted position or fulcrum length.

In one aspect of the invention, the VRBs 1310 may be composed ofthermoplastic polymers, especially high tenacity polymers, include thepolyamide resins such as nylon; polyolefin, such as polyethylene,polypropylene, as well as their copolymers such as ethylene-propylene;polyesters, such as polyethylene terephthalate and the like; vinylchloride polymers and the like, and polycarbonate resins, and otherengineering thermoplastics such as ABS class or any composites usingthese resins or polymers. The thermoset resins include acrylic polymers,resole resins, epoxy polymers and the like.

Polymeric or composite materials may contain reinforcements that enhancethe stiffness or flexure of the flexure resistance spine. Somereinforcements include fibers, such as fiberglass, metal, polymericfibers, graphite fibers, carbon fibers, boron fibers and Nano-compositeadditives, e.g., carbon nano-tubes, et al., to fill the molecular gaps,therefore strengthening the material.

Additional materials that the resistance rods or VRBs 1310 may also becomposed of include high tensile aircraft aluminum and high carbonspring steel and/or high tensile strength to weight materials.

FIG. 12 illustrates an exemplary medical brace in accordance with theprinciples of the invention. In this illustrative example, at least oneVRB 100 is incorporated into a VRB assembly 1215 into an anchor 1230, anadjuster 1220, and a fulcrum 1210. The bracing system in FIG. 12 iscomprised of a thigh leg strap collar 1205 attached to a frame with afulcrum 1210 connected to a hinge 1225 with an upper arm 1240 with abushing piston acting as a second cartilage.

In this illustrative embodiment, VRBs 100 are adjusted to create avariable flex. Element 1205 illustrates leg strap or collar (thigh).Element 1205 a illustrates leg strap or collar (calf). Element 1210illustrates fulcrum for VRB 100 to maintain controlled bending. Element1215 illustrates a VRB assembly (one or more VRB's) that acts as aleaf-spring/unloader; i.e., a first suspension point. Element 1220illustrates VRB assembly adjuster to customize flexibility orresistance. The assembly adjuster 1220 may be a worm gear as previouslydescribed. Element 1225 illustrates a hinge that mimics thebio-mechanical movement or range of an anatomical joint (e.g. knee).Element 1230 illustrates VRB assembly anchor with spring/bushings: i.e.,a secondary suspension point. Element 1240 illustrates a telescopingupper hinge arm with a bushing piston, a second cartilage: i.e., a thirddampening or cushioning point. VRB assemblies 100 a or 1215 provides adynamic supportive structure designed to act as an artificial or secondknee to support a damaged or injured one.

An additional benefit of incorporating the VRB 100 technology intomedical devices is that the resistance rods, under compression, create aproportioned constant vertical lift to unload 1215 and dynamicallysupport the joint (e.g., a knee) during post op, rehabilitation,arthritis or during extreme sports. Hence, the VRB 100 technologydescribed herein provides a truly functional and adjustable brace thatprovides for Shock Absorbing 1215, 1230, 1240, Active Suspension 1215,Adjustable Comfort DST Unloader Knee Brace.

As previously described, resistance ranges are generated by rotating thebeams over a fulcrum positioned adjacent to a body joint.

Dynamic support is also beneficial for the recuperative period followingoperation, rehabilitation, arthritis or during extreme sports.Additionally, resistance beam assemblies may also contribute to shockabsorption via a bushing and piston arm mechanically connected to thebeam assembly. Furthermore, beam assemblies positioned on each side of ajoint act as lateral stabilizers.

In one aspect of the invention, the VRB's 100 may be composed ofthermoplastic polymers, especially high tenacity polymers, include thepolyamide resins such as nylon; polyolefin, such as polyethylene,polypropylene, as well as their copolymers such as ethylene-propylene;polyesters, such as polyethylene terephthalate and the like; vinylchloride polymers and the like, and polycarbonate resins, and otherengineering thermoplastics such as ABS class or any composites usingthese resins or polymers. The thermoset resins include acrylic polymers,resole resins, epoxy polymers, and the like.

Polymeric materials may contain reinforcements that enhance thestiffness or flexure of the flexure resistance spine. Somereinforcements include fibers, such as fiberglass, metal, polymericfibers, graphite fibers, carbon fibers, boron fibers and Nano-compositeadditives, e.g. carbon nano-tubes, et al, to fill the molecular gaps,therefore strengthening the material.

Additional materials that the resistance rods or VRB's may also becomposed of include high tensile aircraft aluminum and high carbonspring steel and/or high tensile strength to weight materials.

Although the different applications of the VRBs shown herein refer toVRB 100 (type I), it would be recognized that each of the applicationsmay incorporate one or more of the other type of VRBs (i.e., type IIthrough type VII) without altering the scope of the invention.

The resilient VRB's shown in herein may be used with or in conjunctionwith sports equipment and exercise apparatus to create meaningfulexercise and or other useful mechanisms. For example, devices suitablefor exercise equipment, sports equipment, home improvement and medicalmobility may be created to selectable control bending strength orresistance ranges to impart performance benefits. VRB's may be securedat one or more fixed points with the appropriate device may be used toprovide appropriate variable resistance. In addition, the VRBs may behandheld at various points along the beam length to affect fulcrumresistance and or rotated to different incremental orientations toaffect resistance with discrete geometric cross sections. In one aspectof the invention, VRB's may be perpendicularly mounted to a variety ofmechanical apparatus to affect resistance and may additionally behandheld in the air to expand the exercise envelop.

The VRB's described herein may be manufactured based on a methodselected from a group consisting of: rapid prototyping,stereolithography, molding, casting, extrusion and other known in theart.

VRBs, which may be solid, semi-hollow or hollow, with or withoutgeometrically created I-beam effect (i.e., spines) on the outside orinterior diameter generates resistance depending on the axis oforientation and/or a fulcrum position has been described herein. VRBs100, with incorporated I-beam geometry on the outside diameter, canallow for the dynamic adjustment of resistance of the device. Anadvantage of a device including a VRBs described herein may be-compact,lightweight and offer the ability to more easily and quickly change adesired level of resistance than is typically found in units usingweights, rubber bands, bows or springs. By simple hand reposition, asshown in FIG. 3, or rotation of beam of the incorporated into the devicea desired resistance level may be achieved. VRBs 100 disclosed, herein,can provide resistance, depending on the orientation of the beam, to theuser. In addition, the device can vary the resistance provided to theuser during an exercise, without interrupting the exercise cycle.Additional beam resistance is achieved depending upon the relativeorientation of the beam within a 180° degree hemisphere of movementrelative to the user. Hence, according to the principles of theinvention, a progressive dynamic resistance may be achieved with avariation of the orientation of the beam or shaft shown herein.

The principle of Progressive Dynamic Resistance (PDR) are:

controlled and rotatable (variable) resistance beam with ergonomic workzones:

Multiple, sequential, mechanical resistances are achieved for thepurpose of rehabilitation and exercising of endo-skeletal musculature.

Increased/decreased incremental mechanical resistance and exerciseadjustability is achieved through beam rotation and or fulcrum handposition relative to the beam or arc length/distance along theresistance beam to impart desired work load.

PDR's 180° or 360° degree range of dynamic arcing motion provides anexercise resistance program for every male or female body type withvariability in muscle size and strength to provide gain after unilateralresistance training of progressive resistance exercise (PRE).

PDR's incremental mechanical resistance capability (i.e., resistanceadjustability through rotation and or fulcrum hand position) facilitatesand customizes the user's strength curve and exercise requirements fromsimply moving hand/leg position to tailor the optimum resistance tomaximize the workout of the targeted muscle group.

PDR resistance beam technology does not have mechanical flat spots ordead spots and provides continuous resistance curve to maximize workoutloading on the targeted muscle groups, thus creating a more effectivework out.

PDR's bend/arc/range of motion means that as the resistance beam is bentfarther away from a plane of minimum resistance, the sustainedmechanical resistance incrementally increases, creating a progressivelymore intense and effective work out/work load on the target musclegroup.

Continuous Progressive Dynamic Resistance loading from the bending ofVRBs 100 is a highly effective bio-mechanical exercise.

In other aspects of the invention, different types of sport equipmentand apparatus may incorporate the VRBs 100 technology described herein.Examples in which VRB 100 technology may be applied are:

FIGS. 3, 4and 5 illustrate an exemplary system in accordance with the principlesof the invention.

FlexBoard product represents an apparatus or structure wherein atransportable structural panel resting on the ground with rod holdersinto which VRB's 100 are inserted perpendicularly to allow users toperform a variety of exercises. FIG. 6 illustrates an exemplaryFlexBoard system in accordance with the principles of the invention.

FlexGym represents an apparatus or structure wherein the VRB 100technology of the present invention may be incorporated into a pluralityof structural tracks with rod holders providing multiple positions intowhich the VRB 100 resilient adjustable or non-adjustable solid ortubular rods and other exercise apparatus are inserted to allow users toperform a variety of exercises in an I-formed structure, with acantilevered bench that folds down or may be a free form bench. Inaddition, the floor tracks, which also comprise the lower structure ofthe unit, can be optionally retracted to the vertical tracks when not inuse.

In one aspect of the invention a means to track and record exercisecycles per set of the user may be incorporated. For example, biometricdata of the user may be recorded on a smart card, a smart phone, acomputer, etc. so exercise cycles can be recorded. In addition,biometric data of the user may be conveyed by magnet, reflector, RFID,WiFi or other means to measure or quantify exercise cycle.

In another aspect of the invention, the exercise apparatus may includesensors (e.g., WiFi) to sense proximity of the user as the userapproaches the exercise apparatus. The sensors may also be incommunication with a user's smart phone transmitter or other technicalmeans and the exercise apparatus respond may be setup to correspond to auser's particular exercise regime.

Another embodiment of the exercise apparatus sensors would recognize auser via sensor or WiFi or iPhone transmitter that would initiateservo-mechanisms to proactively set a customized workout cycle. Thiswould mean that the track holder along the track, be it vertical orhorizontal, and would be matched to the user's ergonomic body size andrequirements.

In another aspect of the invention a video display or monitor may beincorporated to enable a user to receive instructions regarding aparticular exercise or to watch one or more programs of interest duringthe exercise session.

Returning to FIG. 3, FIG. 3 represents a method for incorporating theVRB 100 technology into an apparatus for exercise with one or moreanchor point which is represented by the product FlexToner. Morespecifically, the present invention related to a resilient adjustable ornon-adjustable solid or tubular rod exercise apparatus handheld at oneor more places and flexed.

Other VRB 100 exercise apparatus applications are, but not limited to,upper and or lower body exercise machines: (e.g. treadmills, stairclimbers, elliptical trainers, stationary bikes, mobility, medical,rehabilitative systems that create and control selectable bendingstrength or resistance ranges with fixed rotation to impart PDR)isolating the upper and or lower body for exercise.

The present invention may be incorporated into devices that provide forlow impact/low resistance exercises (e.g., Rehabilitative and Geriatricexercisers) to strengthen and rehabilitate post surgical, bed-ridden,sport injury and or geriatric benefit. Typically, these devices mayemploy VRBs 100 that are matched to the strength of the user. Forexample, VRB 100 may be adjusted to provide rigid support during aninitial healing phase of a sports injury and then adjusted to providelesser amount of support to compensate for progress during the healingof the sport injury.

Although, the present invention is described with regard to a pluralityof different equipment, it would be recognized that the describedequipment are merely examples to which the VRB technology describedherein may be applied. The examples provided herein are merelyillustrative of the application of the claimed technology and theexamples are not intended to limit the subject matter claimed.

In other aspects of the invention, other types of sports equipment andapparatus may incorporate the VRB 100 technology described herein.Examples in which VRB 100 technology may be applied are, but not limitedto:

Golf Clubs

Golf clubs may be formed of graphite, wood, titanium, glass fiber orvarious types of composites or metal alloys. Each varies to some degreewith respect to stiffness and flexibility. However, golfers generallycarry onto the golf course only a predetermined number of golf clubs.

Varying the stiffness or flexibility of the golf club is not possible,unless the golfer brings another set of clubs of a differentconstruction. Even in that case, however, the selection is stillsomewhat limited.

Nevertheless, it is impractical to carry a huge number of golf clubsonto the course, each club having a slight nuance of difference inflexibility and stiffness than another. Golf players prefer taking ontothe course a set of clubs that are suited to the player's specific swingtype, strength and ability.

Returning to FIG. 8, which illustrates an exemplary embodiment of aninternal VRB 100 in a hollow shaft (e.g., a golf shaft). As previouslydiscussed, the VRB 100 is centrally raised or lowered within the golfshaft, the fulcrum or kick point is raised or lowered, thereby changingthe shaft flex. The 360 degree symmetrical geometry provides a solutionfor an adjustable golf club and would be fully compliant with theexisting USGA rules of golf and assorted international golfassociations.

Running Shoes, Training Shoes, Basketball Shoes

The transmission of the shoe wearer's strength (power) from their legsinto the ground is directly affected by the sole stiffness of the shoe.Runners may gain more leverage and, thus more speed, by using a stiffersole. Basketball players may also affect the height of their jumpsthrough the leverage transmitted by the sole of their shoes. If the soleis too stiff, however, the toe-heel flex of the foot is hindered.

It is advantageous that the shoe wearer have the ability to tailor thesole stiffness to his/her individual weight, strength, height, runningstyle, and ground conditions. Preferably, the shoe wearer may tailor thestiffness of the shoe sole to affect the degree of power and leveragethat is to be transmitted from the wearer into the ground.

In this example, VRBs 100 are insertable, insert molded or structurallyconnected to the shoe sole in lateral and/or longitudinal positionswithin the sole and are all rotatable to a fixed and mechanically lockedposition to effect custom flexural resistance range. Additionally, zonesof resistance are customizable, e.g. the right pad of the foot can bemade more rigid than the left pad side through the beam's rotatedorientation. Thus, the degree of flexibility may be customized toaccommodate a user's desired preferences.

Incorporation of the VRB 100 technology into running shoes, as shown inFIG. 11, provides a dynamic adjustable in-sole suspension system thatcan absorb the weight of the wearer and release it per each step.

Hockey Sticks

Hockey includes, but is not limited to, ice hockey, street hockey,roller hockey, field hockey and floor hockey.

Hockey players may require that the flexure of the hockey stick bechanged to better assist in the wrist shot or slap shot needed at thatparticular junction of a game or which the player was better at making.Players may not usually leave the field to switch to a different pieceof equipment during play.

Younger players may require more flex in the hockey stick due to lack ofstrength and such flex may mean the difference between the youngerplayer being able to lift the puck or not when making a shot since astiffer flex in the stick may not allow the player to achieve such lift.

In addition, as the younger players ages and increases in strength, theplayer may desire a stiffer hockey stick, which in accordance withconvention means the hockey player would need to purchase additionalhockey stick shafts with the desired stiffness and flexibilitycharacteristics. Indeed, to cover a full range of nuances of differingstiffness and flexibility characteristics, hockey players would haveavailable many different types of hockey sticks.

Even so, the hockey player may merely want to make a slight adjustmentto the stiffness or flexibility of a given hockey stick to improve thenuances of the play. Thus, the incorporation of the VRB technology intohockey sticks (shaft and/or blade) provides for variations in thestiffness and flexibility that may be adjusted as the user progresses intheir ability.

Incorporation of the VRB technology into hockey sticks is similar tothat shown in FIG. 7.

In other aspects of the invention, different type of Do-it-Yourself(DIY) and Home Improvement products and devices may incorporate the VRBtechnology described herein. Examples in which VRB technology may beapplied are: Lawn Equipment:

Adjustable lawn rake with VRB 100 tines:

The VRB 100 technology described by the present invention may beincorporated into a lawn rake. In this case, an adjustable rake with arotatable VRB 100 down the shaft of the rake may be created. The VRB 100facilitates the adjustment of the lawn rake, with the ability to adjuststiffness of the shaft relative to the load (e.g., light grassclippings, heavy grass clipping, wet grass clippings).

Incorporation of the VRB 100 technology into lawn rake (or other similarhandled devices) is similar to that shown in FIG. 10A and FIG. 10B.

In another embodiment, the VRB 100 technology described by the presentinvention may be incorporated into tines of a lawn rake creating anadjustable rake. Thus, the VRB 100 facilitates the adjustment of alawn/utility rake by providing the ability to create variable shaftresistance for light or heavy duty gravel raking due to its rotatedorientation. The VRB 100 adjustment setting may simultaneously rotatethe rake's tines from 0° to 90°, thus affecting a stiffer tineorientation. The tines may be elliptical or oval in shape in anembodiment of an elliptical VRB 100. When the tines are in a 0°orientation, they are the most flexible and suitable for raking leavesor light duty yard work. When the tines are in a 90° orientation, theyare the most rigid and suitable for raking heavy duty gravel. Theflexural change of tines can be further impacted by means of adjustingwhere the center point of a fulcrum of the flex of tines is located.

FIG. 10A illustrates an exemplary lawn rake incorporating the VRB 100technology disclosed herein. FIG. 10A and FIG. 10B illustrates a rakeassembly 1000 including a handle 1010 and a tine assembly 1015 includinga plurality of VRB 100 tines that are simultaneously adjusted throughrotation. FIG. 10B illustrates a bottom view of rake 1000 showing theorientation of the tines 100 at a maximum resistance level (90 degreeorientation).

Thus, the incorporation of the VRB 100 technology in the tines creates aflexible lawn rake to alter the flex characteristics of the rake.

Although, the present invention is described with regard to a pluralityof different lawn equipment, it would be recognized that the lawnequipment described herein are merely examples to which the VRBtechnology described herein may be applied.
